Hah, Petluvr, love the new avatar!
Anyway, I don't really like to use flake because I do notice that the fish don't seem to get all of it before it gets pushed down by the filter out put or gets waterlogged. Unlike pellets and wafers, the flake breaks up really easily, and my fish don't seem to see it to pick at it and eat it up once on the substrate, plants, etc.
I noticed that it helped a lot to breakup the feed into 2-3 parts. I'd feed 1/2 to 1/3 of the flake, wait until that was gone, and then feed the next portion. That really cut down on the missed flake. It wasn't necessarily overfeeding, but more like too much food all at once. I hadn't been overfeeding; the fish just couldn't eat it all before the filter sucked it down. I had a lot of filtration on that tank.
